Before activating your cycling computer, measure the wheel size of your bicycle.

Measuring Wheel Size

Wheel size settings are a prerequisite for correct cycling information. There are two ways of determining the wheel size of your bike:

Method 1

Look for the diameter in inches or in ETRTO printed on the wheel. Match it to the wheel size in millimeters in the right column of the chart.

ETRTO	Wheel size diameter (inches)	Wheel size setting (mm)

25-559	26 x 1.0	1884
	26 x 1.0	1884

23-571	650 x 23C	1909
	650 x 23C	1909

35-559	26 x 1.50	1947
	26 x 1.50	1947

37-622	700 x 35C	1958
	700 x 35C	1958

47-559	26 x 1.95	2022
	26 x 1.95	2022

20-622	700 x 20C	2051
	700 x 20C	2051

	26 x 2.0	2054

	700 x 23C	2070

	700 x 25C	2080

28-622	700 x 28	2101
	700 x 28	2101

32-622	700 x 32C	2126
	700 x 32C	2126

42-622	700 x 40C	2189
	700 x 40C	2189

47-622	700 x 47C	2220
	700 x 47C	2220

Wheel sizes on the chart are advisory as wheel size depends on the wheel type and air pressure.

Method 2

Measure the wheel manually for the most accurate result.

Use the valve to mark the point where the wheel touches the ground. Draw a line on the ground to mark that point. Move your bike forward on a flat surface for one complete rotation. The tire should be perpendicular to the ground. Draw another line on the ground at the valve to mark a full rotation. Measure the distance between the two lines.

Subtract 4 mm to account for your weight on the bike to get your wheel circumference. Enter this value in the cycling computer.

Basic Settings

Before using your cycling computer for the first time, customize the basic settings. Enter as accurate data as possible to ensure correct feedback based on your performance.
